Description

Technical Field

[0001] The utility model relates to the technical field of Caulerpa lentillifera cultivation, in particular to a liftable Caulerpa lentillifera cultivation frame. Background Technique

[0002] Caulerpa lentillifera is commonly known as sea grapes, belonging to the Chlorophyta, Caulerpaceae, Caulerpa genus, and is a high-grade edible seaweed. Because the spherical branches on its upright stems are round and full in appearance, with attractive colors, like strings of grapes crystal clear, it is named "sea grapes", and because it has the unique taste and texture of caviar, it is known as "green caviar". Because it contains rich nutrients in its body, such as soluble Caulerpa polysaccharide, carotene, algal protein, various unsaturated fatty acids, etc., it has great development potential in food, health products, medicine and other aspects.

[0003] In the process of cultivating the existing sea grapes, the control of light is not strict enough. If the sea grapes are exposed to excessive light, it is easy to cause microalgae to grow on the surface of the sea grapes. If the amount of light irradiated on the sea grapes is insufficient, it will affect the growth of the sea grapes and the cultivation quality of the sea grapes. For this reason, we propose a liftable Caulerpa lentillifera cultivation frame. Content of the Utility Model

[0004] The purpose of the utility model is to provide a liftable Caulerpa lentillifera cultivation frame to solve the above deficiencies in the technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: a liftable Caulerpa lentillifera cultivation frame, including a cultivation pool, a net box is arranged inside the cultivation pool, vertical PVC fixing pipes are fixedly arranged on the outer walls of the four corners of the net box, fixing rings are fixedly arranged at one ends of the tops of the four PVC fixing pipes, positioning rods are inserted between adjacent fixing rings, a bridge is fixedly arranged on the top outer wall of the cultivation pool through a bracket, fixed pulleys are fixedly arranged on the bottom outer walls of the two bridges, two fixing piles are respectively fixedly arranged on both sides of the top of the cultivation pool, hanging rings are fixedly arranged on the outer walls of the two positioning rods, a traction rope is bolted to the outer wall of the hanging ring, and one end of the traction rope passes through the outer wall of the fixed pulley and is tied to the outer wall of the fixing pile.

[0006] Preferably, scale wire grooves are engraved on the outer wall of the PVC fixing pipe, and through the scale wire grooves, it is convenient to observe the depth of the utility model in the cultivation pool.

[0007] Preferably, external thread fixing columns are fixedly arranged at one ends of the bottoms of the four PVC fixing pipes, a positioning disc is arranged at the bottom of the PVC fixing pipe, a cross-shaped bracket is fixedly arranged on the outer wall of the positioning disc, a positioning hole is opened on the outer wall of one end of the cross-shaped bracket, the external thread fixing column is inserted into the inner wall of the positioning hole, and a nut is screwed on the outer wall of the external thread fixing column.

[0008] Preferably, a counterweight ball is fixedly provided on the outer wall of the bottom of the positioning disc, and is fixed to the bottom of the net cage through the counterweight ball, which is beneficial to improving the stability during the lifting and lowering process of the net cage.

[0009] Preferably, the size of one side of the net cage is 2m × 1m.

[0010] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0011] By untying the towing rope bolted to the fixed pile and cooperating with the fixed pulley, the sea grapes descend inside the cultivation pond, increasing the cultivation depth of the sea grapes and reducing the illumination effect received by the sea grapes, which can avoid the overgrowth of microalgae on the surface of the sea grapes. By pulling the towing rope and cooperating with the fixed pulley to lift the net cage from the cultivation pond, the cultivation depth of the sea grapes is reduced, and the effect of the sea grapes receiving light irradiation is increased, which can ensure the normal growth of the sea grapes. By adjusting the cultivation depth of the sea grapes, it is beneficial to improve the cultivation quality of the sea grapes. Description of the Drawings
